The incident took place at 6:09 pm (IST) in a local train from Churchgate to Borivali between Khar and Mahim stations on the Western Line. The second blast was reported at Bandra station, while the third blast took place at Matunga. Soon after, the fourth explosion took place at Jogeshwari, while two blasts were reported in Borivali.

The seventh blast was reported from Bhayandar station near Mira Road, while the eighth blast took place at Santacruz Station. Police suspect that it is a pre-planned subversive plot similar to the explosions that had rocked Mumbai in 1993, 2002 and 2003.

All suburban and long-distance trains on the Western railway lines were suspended. Police have also cordoned off the major road intersections, railway stations and exit points. Many commuters were stranded after the explosions and additional buses have been deployed in Mumbai to cope with the situation.

The blasts were targeted at commuters in the suburbs. It took place in the first class coaches during rush hour. Mumbai airport has also been put on alert. Some of the injured have been taken to Lilavati hospital while others have been taken to Cooper and Hinduja hospitals. Many others have also been admitted to KEM Hospital, V N Desai Hospital and Bhabha Hospital.

The IB is probing the link between the blasts at Srinagar and Mumbai, and also looking at possible link with PoK polls. The Mumbai police were also probing links between the Mumbai blasts and the seizures of two suspected Lashker-e-Taiba modules early this year.
